KEY POINT
- Heidi Klum surprised Henry with a Ferrari F430 for his 21st birthday.
- The gift fulfilled a Mario Kart bet Henry made with Tom Kaulitz seven years earlier.
- Klum said Kaulitz kept his promise, while describing her children as grounded and hardworking.
Heidi Klum marked her son Heidi Klum with a surprise that had been years in the making. In an Instagram video shared Saturday, September 12, Klum showed Henry the birthday present waiting in the driveway.

The model and television personality told her son she could hardly believe he had reached the milestone, reminding him that he had been waiting for the gift for many years. The camera then revealed the present: a Ferrari F430 purchased by Klum and her husband, Tom Kaulitz.
The luxury car was not simply an unexpected birthday present. It fulfilled an agreement Henry had made with Kaulitz when Henry was 14.
The Mario Kart Bet Behind the Gift
The unusual promise began with a game of Mario Kart. According to throwback footage Klum shared on Instagram, Henry had proposed a wager with Kaulitz tied to a Christmas game.
Under the terms Henry described, losing would mean giving up video games for three months and creating a painting of himself driving. Winning, however, came with a much bigger prize: Kaulitz would have to give Henry a Ferrari when he turned 21.
Seven years later, that promise became reality.Klum highlighted the length of time between the original wager and Henry’s birthday, while also noting that Kaulitz had followed through on his commitment.
Henry’s Interest in Cars
The Ferrari gift also reflects an interest Henry shares with Kaulitz. Klum previously described the pair’s relationship around cars, saying Henry enjoys talking about them with her husband.

For Klum, those conversations are less familiar territory. She said that when the discussion turns to cars, she tends to tune out while Henry and Kaulitz can discuss the subject in much greater detail.
That shared interest has given Henry and Kaulitz another point of connection within Klum’s family.
Klum on Her Children’s Work Ethic
Klum has also spoken about the values she wants her children to carry with them. She said her children have seen the amount of work behind her public career rather than only the glamorous side of it.
She pointed to conference calls with producers, developing concepts and photo shoots as examples of the work her children have witnessed. Klum said family dinners have also been a regular setting where everyone discusses their day.
Those conversations have included stories from her career and experiences with entertainers such as Snoop Dogg and Tiësto, moments that have prompted surprised reactions from her children.
Henry is one of four children Klum has raised across her family relationships. She shares Henry, Johan and Lou with her former husband, Seal, while her eldest daughter, Leni, is from her previous relationship with Flavio Briatore.
Klum married Kaulitz in 2019, and his relationship with her children has become part of their family dynamic. His shared interest in cars with Henry has been one example of that bond.
For Henry, the birthday surprise represents more than a high-profile gift. The Ferrari fulfills a promise that began with a childhood video-game bet and remained in place until his 21st birthday.
The story also gives a glimpse into the family relationship between Henry and Kaulitz, whose shared enthusiasm for cars helped turn an old Mario Kart wager into a memorable milestone celebration.
